A wind turbine includes a nacelle with a main bearing tilted with its rotation axis towards the horizontal axis and including an inner and outer ring, wherein the main bearing is a slide bearing and the inner ring is stationary while the outer ring rotates, with the main bearing being lubricated, and with the outer ring including a first and a second sealing means, wherein the first sealing means is due to the tilt of the main bearing lower than the second sealing means, wherein a stationary leakage lubrication fluid collection means is provided adapted for collecting lubrication fluid, wherein the outer ring is provided with one or more axial bores connecting a leakage lubrication fluid collection area to the leakage lubrication fluid collection means and wherein each sealing means includes a groove accommodating a sealing element and a sealing element carrier ring.
A wind turbine comprising a nacelle with at least one main bearing tilted with a rotation axis towards a horizontal axis and comprising an inner ring and an outer ring, wherein the at least one main bearing is a slide bearing and the inner ring is stationary while the outer ring rotates around the inner ring, with the at least one main bearing being lubricated with a lubrication fluid, and with the outer ring comprising a first sealing means and a second sealing means arranged at both sides of the outer ring for sealing to the inner ring and extending around the outer ring, wherein the first sealing means is due to the tilt of the at least one main bearing lower than the second sealing means, wherein a stationary leakage lubrication fluid collection means is provided adjacent to the first sealing means adapted for collecting lubrication fluid leaking from the first sealing means and the second sealing means, wherein the outer ring is provided with one or more axial bores connecting a leakage lubrication fluid collection area adjacent to the second sealing means to the stationary leakage lubrication fluid collection means and wherein each sealing means comprises a groove accommodating a sealing element and a sealing element carrier ring having a fold and a clamp ring attached to the sealing element carrier ring closing the fold to build the groove and clamping the sealing means in the groove.
A main bearing for a wind turbine, comprising an inner ring and an outer ring, wherein the main bearing is a slide bearing and the inner ring is adapted to be stationary while the outer ring is adapted to rotate around the inner ring, with the main bearing being lubricated with a lubrication fluid, and with the outer ring comprising a first sealing means and a second sealing means arranged at both sides of the outer ring for sealing to the inner ring and extending around the outer ring, wherein an associated stationary leakage lubrication fluid collection means is provided to be arranged adjacent to the first sealing means, which associated stationary leakage lubrication fluid collecting means is adapted to collect lubrication fluid leaking from the first sealing means and the second sealing means, wherein the outer ring is provided with one or more axial bores connecting a leakage lubrication fluid collection area adjacent to the second sealing means to the associated stationary leakage lubrication fluid collection means and wherein each sealing means comprises a groove accommodating a sealing element and a sealing element carrier ring having a fold and a clamp ring attached to the sealing element carrier ring closing the fold to build the groove and clamping the sealing means in the groove.
